On Friday, Carnegie Institution of Washington and M7D—the legal name of WD Lab Grown Diamonds—dismissed their patent infringement suit against ALTR Created Diamonds and parent company R.A. Riam.
The case, originally filed in January in New York federal court, was dismissed without prejudice, leaving open the possibility it could be refiled.
ALTR declined comment.
WD chief executive officer Sue Rechner tells JCK viaemail, “We can’t comment on ongoing legal matters. We will certainly reach outas soon as we are able to share any information on the situation.”
The case was one of three suitsthat WD filed last month. At press time, Carnegie Institution and WD still hadcases pending against two other pairs of lab-grown diamond companies: PureGrown Diamonds and sister company IIa Technologies, based in Singapore; andFenix Diamonds and owner Mahendra Brothers, based in Mumbai, India.
Like its now-dismissed caseagainst ALTR, the suits charge those companies with infringing on Carnegie’spatents for growing diamonds with the chemical vapor deposition (CVD) methodand treating the diamonds after they are grown. M7D has licensed growingand treating technology from the Carnegie Institution since 2011.
At press time, the other cases have not been dismissed, and thedefendants have not responded to the complaints.
At press time, Mahendra and Fenix had not filed any documentswith the court.
On Tuesday, Pure Grown and IIa’s attorneys filed a corporate disclosure statement, saying that Pure Grown’s corporate parent is Iron Gate Property Limited Inc., which, according to public records, is based in Panama. IIa Technologies’ corporate parent is Spring Field Group Limited B.V., which records say is based in Curaçao.
Its attorneys did not return a request for comment.
Last month, a Singapore court ruled that IIa Technologies had violated a diamond-growing patent held by De Beers–owned industrial diamond producer Element Six. It also revoked one of Element Six’s patents for treating lab-grown diamonds with the high pressure, high temperature method.
Both parties say they areexploring their options and whether to appeal. IIa has denied any infringement.
On Feb. 20, De Beers CEO Bruce Cleaver Said: “We havesimilar patents in the United States. We are now going through a range ofoptions of what we will do in the United States. That is a potential storycoming up.”
